Defense against rare but cataclysmic events

A fascinating technical/scientific piece about the destructive power of asteroids and a simple strategy to defend Earth from them:

Bottled water is evil

Levitation (yes, for real!)

Think levitation would be cool? Well, someone figured out how to do it. And this isn't just theoretical, this is a working proof-of-concept:

... and here's a longer video, with more examples and an overly-simplistic explanation:

For more info, check out the Quantum Levitation website.

The shift to Big Data

Businesses are starting to realize that the key to becoming competitive is knowing how to analyze all the data they have available. This means a shift in what skills are valuable to a company:

Then the third thing, which is the subtlest but perhaps the most important, is cultural change about how to use data. A lot of companies think they’re using data, and you often see bar charts and pie charts and numbers in management presentations. But, historically, that kind of data was used more to confirm and support decisions that had already been made, rather than to learn new things and to discover the right answer. The cultural change is for managers to be willing to say, “You know, that’s an interesting problem, an interesting question. Let’s set up an experiment to discover the answer.”

Want a degree that makes you marketable? Try sociology or psychology:

Having enough data to get a statistically significant result is not a problem. There’s plenty of data. So the skills often have more to do with sampling methodologies, designing experiments, and working these very, very large data sets without becoming overwhelmed. If you look inside companies, you also see a transformation in the functions that are using data.

We've definitely entered an era where the computer is just a tool; programmers are not the millionaires of the future, they are the blue-collar workers. The people who know how to make sense of the data are the ones who will define (and are already building) the next generation of wealth.

It's time to think about changing time

It's that time of year again, time to fall back (at least if you are in the US... well, some parts of the US):

Responsible spending

So here's on of my pet peeves: we want to think we're rational, then we go do stupid stuff like this (click image for full-size):

How rational is it to spend 25 times as much on something that is almost 2000 times less likely to occur? Answer: it isn't.

And if you are tempted to say something like "Yeah, but we got Bin Laden, the war is working!", well, then, I suggest you read The Starfish and the Spider. In any case, even if we did stop terrorism (which we didn't), we've got much bigger daily threats to our lives that we're ignoring. This graph hopefully puts one of them in perspective.

Lifting the lid on bad science

Bed Goldacre demonstrates some of the most distorting ways bad science is being used in medicine a pharmaceuticals and offers ideas for a solution:

Lots about how hearing works

A fantastic talk about the necessary evolution of cities in light of the current state of the earth:
